Abstract
Objective To evaluate risk factors for central venous catheter-related bloodstream infection(CRBSI)in intensive care unit(ICU)patients by Meta analysis. Methods Literatures about risk factors of CRBSI in ICU pa-tients were retrieved from databases of Cochrane Library,PubMed,Embase,CBM,CNKI,and WanFang Data,RevMan 5.3 software was used for Meta analysis.Results There are 12 literatures in accordance with the inclusion criteria,with a total sample size of 14 422 cases,5 cohort studies and 7 case-control studies,the Newcastle-Ottawa Scale(NOS)scores were 4-6 points. According to Meta analysis,duration of indwelling catheter(WMD,12.25 [95%CI,5.55-18.94]),multi-cavity catheter(OR,3.52[95% CI,1.46-8.52]),femoral vein catheterization (OR,2.44[95%CI,1.34-4.46]),parenteral nutrition(O R,2.47[95% CI,1.18-5.21]),length of stay in ICU(WMD,10.01[95%CI,4.17-15.85]),APACHE II score(WMD,4.46[95%CI,1.25-7.66]),and dia-betes mellitus(OR,1.83[95% CI,1.08-3.09])were significantly different in each group(all P<0.05). Conclusion Risk factors for CRBSI in ICU patients are duration of indwelling catheter,multi-cavity catheter,femo-ral vein catheterization,parenteral nutrition,length of stay in ICU,APACHE II score,and diabetes mellitus. However,due to the limitation of methodological quality of included studies,more strictly designed and large sam-ple prospective studies are needed to verify the result.关键词
